The canton of Reference – It's not the latest Swiss county but Canton's new 8-deep Reference range from Germany. Shown is the Reference 9, a 17.4cm two-way monitor with 25mm tweeter. Across the range, the aluminium midranges and woofers take a page from the Børresen, Monitor & Raidho cookbook by galvanically converting one fourth of their membranes to ceramic then optimizing this harder surface further with the bombardment of wolfram and other metal particles. The Reference series spans from €3.6K for the monitor to €20K for the top floorstander. It includes a 30.8cm subwoofer with passive radiator and a center channel. Finish options are gloss white or black.
